If you are talking about that specific resort, I don't know the answer.
Does the exchange confirmation have a unit number?
At resorts in general, I don't believe many discriminate against RCI, although I just did have a bit of a run-in with the general manager at a FL resort where he made it perfectly clear, in no uncertain terms, that he does discriminate against RCI guests. Matters of that nature should be reported to RCI, as I have, and we are still waiting for the resort's response.
Back to room assignments, the only way we have ever gotten lesser rooms in our 100 exchanges was through lack of knowledge on our part. Most exchanges are into specific units. You can call RCI and find out which units are Spacebanked. When you get familiar with a resort, you can pass on units you don't like until they have one you like.
Be bold, take charge. The first time I considered an exchange into a resort we had never been, and that since become one of our favorites, I called the resort. When they answered I said, "Is there an owner standing around?" There was and I asked him how the resort was oriented and what rooms had what views.
Now I know only to take units ending in 5, 6 7 or 8. 1, 2, 3 and 4 are parking lot views and the others are water views.
In the majority of exchanges, you get the unit you exchanged for, the unit the other RCI member deposited.
In the resorts that assign units, normally the week of checkin, it can be a crapshoot, but we have done well at them, too, typically getting the best units.
So, from my take. RCI folks getting the scraps is just an urban myth. Well, sometimes suburban, sometimes country, sometimes beach, sometimes lake, sometimes golf course . . .
